Furthermore, in PD‐L1‐positive LUAD sufferers, the PD‐L1 level was connected with T stage (tumor size stage), specifically, when compared to patients at T1 stage (tumor size of primary tumor ≤3 cm) (n = 7), the patients at T2 or T3 stage (T2, tumor size = 3–5 cm, n = 10; T3, tumor size >7 cm, n = 15) showed an increased PD‐L1 highly positive rate and a decreased PD‐L1 weakly positive rate (p < 0.01) (Figure 2C). Here, CD274 is linked to neoplasm.
